4-TERMINAL SURFACE MOUNT
SF SERIES
TYPICAL PERFORMANCE SPECIFICA TIONS
* SFG2 capable of 3W dissipation with consideration of pcb layout and pad geometry
RCD’s Series SF resistors feature an all-welded “Kelvin” 4-
terminal design in a surface mount package, reducing the
effects of lead resistance. High -temperature case provides
excellent environmental protection. Series SF utilizes the
same technology as our popular Series L VF leaded
resistors with over 30 years of proven experience.
